Abstract
Description
- This invention concerns a method to produce a composite yarn consisting of textile threads and metallic wire and concerns also the composite yarn thus produced, as set forth in the respective main claims.
- The composite yarn thus produced is employed in the manufacture of knitted underwear and outer knitted garments,, shirts, jeans, furnishing fabrics, curtains, blankets, carpets and other textile products.
- The state of the art covers various types of composite yarns consisting of a metallic wire associated with one or more textile threads. These composite yarns are employed in the manufacture of fabrics, knitted goods, carpets, etc. which possess the properties of providing screening against electromagnetic waves or antistatic properties and earth the body of the person who wears clothes made with such fabrics.
- Moreover, these composite yarns are also employed in the production of fabrics that reduce physical pains associated with the breaking of bones inasmuch as they make normal the electrical charge of the body and reduce the differences of potential occurring in the body, for these differences of potential are the cause of pains due to the breaking of bones.
- The philosophies which lead to the composite textile-metallic yarns are substantially two in number and affect the conformation of the metallic component.
- A first philosophy provides for the use of segments of metallic wire which are assembled with the textile fibre component.
- A second philosophy, from which this invention is derived, provides for the use of one or more continuous metallic wires.
- The present invention is concerned with composite yarns employing continuous metallic wire.
- The prior art document IT-BZ-92A000019 discloses a composite yarn in which at least two textile threads are wound on a taut metallic wire, which stays substantially straight substantially in the centre between the two textile threads.
- This kind of yarn can be made only with a cording machine of the type used to produce cords or with a braiding machine.
- The use of these machines entails a high production cost since these machines are very slow and therefore have a low output.
- Other prior art exists which discloses the winding of one or more textile yarns together with metallic wire; one method of the prior art is to wind together long textile fibres or very fine textile threads with metallic wires so as to produce a composite yarn in which the metallic wire is positioned at random in the composite yarn.
- This means that the metallic wire can come readily to the surface of the composite yarn, thus creating problems of use of the metal and problems of allergy and of suitability to be worn.
- Another method of the state of the art is to wind together textile threads and metallic wire, the metallic wire being alone by itself or combined with a textile filament; the composite yarn thus produced does not ensure that the metallic wire becomes located in a protected and covered position within the composite yarn, and this fact too creates problems of use of the metal and problems of allergy and of suitability to be worn.
- Neither of these methods ensures that the metallic wire does not come to the surface during the successive processing of the composite yarn and does not create problems and possible breakages of the metallic wire during such successive processings.
- Both of these production methods involve also problems of production, output and cost.
- The present applicants have studied, tested and obtained this invention so as to overcome the shortcomings of the state of the art and to achieve further advantages.
- This invention is set forth and characterised in the main claims, while the dependent claims describe variants of the idea of the main solution.
- The method according to the invention enables a composite yarn to be produced from a continuous metallic wire and at least two textile threads, the textile threads having a metric number (Nm) between 7,000 and 200,000 metres per kilogram.
- The continuous metallic wire has a diameter which may vary between 0.010 mm. and 0.100 mm., depending on the final method of use of the composite yarn.
- The metal of which the metallic wire consists will be suitable for the end use of the textile product and therefore may be stainless steel, copper coated with silver and/or gold, aluminium which has been surface-passivated, etc.
- The metallic wire may possibly be coated with a resin, which advantageously is of a conductive type.
- According to a variant the metallic wire is replaced by a metallic strap.
- According to a further variant the metallic strap replacing the metallic wire has on one or both of its sides a protective adhering film of polyester, viscose or nylon.
- According to another variant the metallic wire or metallic strap has a cross-section of a polygonal shape.
- The method according to the invention arranges for the metallic wire and textile threads to undergo a first coupling operation in which the threads and wire are united according to a desired reciprocal positioning.
- The coupled threads and wire which have their axes substantially parallel and linear then undergo a twisting step in which the metallic wire and textile threads are bonded together by a number of required twists about the lengthwise axis of the resulting composite yarn.
- In the method according to the invention the metallic wire and the textile threads themselves undergo twisting.
- The metallic wire coupled with two textile threads becomes located in a lateral position covered by the two coupled textile threads, so that the coupled metallic wire according to the invention is within the outer periphery of the finished yarn.
- These coupling and twisting operations can be carried out with the normal coupling and twisting machines used at present in the processing of textile threads, thus enabling normal and very versatile machines to be employed with high speeds of output and high outputs of the composite yarn according to the invention to be ensured at a low cost.
- Moreover, with such machines it is possible to use textile threads having a metric number between 7,000 and 200,000 metres per kilogram without thereby involving an appreciable drop of the output of the machines.
- The properties of the metallic wire and textile threads employed and also the parameters of the twisting step vary according to the end use of the composite yarn according to the invention.
- As an example we give below some data of some possible compositions of the composite yarn according to the invention as employed in particular to produce:
- knitted underwear:
1 metallic wire having a diameter of 0.025 mm.;
2 textile threads having a metric number of 70,000 metres/kg.;
the number of twists imparted to the composite yarn is within the range of 500 to 800 twists per metre; - shirts:
1 metallic wire having a diameter of 0.010 to 0.015 mm.;
2 textile threads having a metric number within the range of 140,000 to 200,000 metres/kg.;
the number of twists imparted to the composite yarn is within the range of 800 to 1000 twists per metre; - woollen garments, inserts for blankets:
1 metallic wire having a diameter of 0.025 to 0.040 mm.;
2 textile threads having a metric number of 40,000 metres/kg.;
the number of twists imparted to the composite yarn is within the range of 300 to 500 twists per metre; - light carpets, furnishing fabrics:
1 metallic wire having a diameter of 0.08 to 0.10 mm.;
2 textile threads having a metric number within the range of 7,000 to 20,000 metres/kg.;
the number of twists imparted to the composite yarn is within the range of 150 to 350 twists per metre. - The attached figures are given as a non-restrictive example and show a preferred solution of the invention as follows:
- Fig.1
- is a block diagram of the method to produce a composite yarn according to the invention;
- Fig.2
- gives a view of a yarn consisting of a metallic wire and two textile threads and made with the method according to the invention;
- Fig.3
- shows in an enlarged scale a cross-section along the line A-A of the composite yarn of Fig.2.
- The
reference number 10 in the attached figures denotes generally a method to produce acomposite yarn 11 consisting of ametallic wire 12 and at least twotextile threads 13. - The
method 10 to produce acomposite yarn 11 according to the invention includes afirst coupling step 14 in which the continuousmetallic wire 12 is caused to cooperate with at least twotextile threads 13 so as to produce a coupledthread 15 that comprises at least twotextile threads 13 and at least onemetallic wire 12. - The coupling of the wire and threads takes place by first coupling the two textile threads and then by doubling the metallic wire with the coupled threads, taking care to place the
metallic wire 12 between the twotextile threads 13 in thefirst coupling step 14. - This
coupling step 14 may be carried out with the common coupling machines employed in the traditional textile industry. - The coupling machines employed may be of the type with a thread-guide or of the type with a grooved roller.
- The
textile threads 13 orwire 12 are advantageously unwound by being drawn from a hank positioned on a stationary swift. - In fact, the unrolling of the
textile threads 13 ormetallic wire 12 from a hank positioned on a rotary swift leads in this case to lower unwinding speeds than is the case with unwinding from a stationary swift and therefore reduces the output of the machines. - Moreover, unrolling the
metallic wire 12 from a rotary swift not only leads to the above problems of lower speeds but is also not employed owing to the fact that it induces in themetallic wire 12 tensions which tend to lengthen themetallic wire 12 and to reduce the percentage of plastic elongation which is required of thecomposite yarn 11 in the successive processes. - It should be noted that the invention arranges that in every successive step in the production of the composite yarn there is always unwinding from a hank positioned on a stationary swift.
- In fact, to make possible the successive processings of the
composite yarn 11 and to ensure that the finished fabric made with thecomposite yarn 11 behaves substantially like a fabric made oftextile threads 13 alone, it is necessary to ensure a minimum percentage of elongation in thecomposite yarn 11. - The coupled
thread 15 undergoes thereafter a twistingstep 16, in which themetallic wire 12 andtextile threads 13 forming the coupledthread 15 are bonded together by imparting a desired number of twists which wind themetallic wire 12 andthreads 13 about the lengthwise axis of thecomposite yarn 11 thus produced. - This
second twisting step 16 can be carried out with the common twisting machines employed in the traditional textile industry. - The
metallic wire 12 has a diameter which may vary from 0.01 to 0.10 mm. depending on the end use of thecomposite yarn 11, while thetextile threads 13 employed have a metric number between 7.000 to 200.000 metres/kg. - Furthermore, the number of twists imparted to the coupled
thread 15 in the twistingstep 16 will vary according to the end use of thecomposite yarn 11 and will generally range from 150 to 1000 twists per metre. - In the
composite yarn 11 according to the invention themetallic wire 12 and thetextile threads 13 undergo the twistingstep 16 and are therefore spirally arranged about an ideal axis. - Where the
composite yarn 11 according to the invention consists of ametallic wire 12 coupled to and twisted with twotextile threads 13, themetallic wire 12 becomes positioned in a lateral position in the zone of mutual support of the twotextile threads 13. - The
metallic wire 12 becomes located in particular in an internal recess within a substantially V-shapedspace 17 created at the point of mutual contact of the two twisted textile threads 13 (see Fig.3). - This positioning, owing to the method employed, entails protection of the
metallic wire 12 by being covered by part of the twotextile threads 13, which cover themetallic wire 12 at least partly. In any event thetextile threads 13 create protective spines at the two sides of themetallic wire 12, so that themetallic wire 12 does not emerge from the spines of thetextile threads 13. - This means that in the successive operations and in the finished product the
metallic wire 12 practically never emerges from thecomposite yarn 11, thus preventing themetallic wire 12 causing problems in the successive processings of thecomposite yarn 11. - In fact, the
metallic wire 12 is sunk in the textile yarn which thus acts as a protection, insulation and elastic absorption of the mechanical tensions which may occur in themetallic wire 12. - It should be noted that a fabric made with the yarn according to the invention behaves, when in contact with the skin, like a normal textile fabric since the textile threads are the threads which come in contact with the skin, and at the same time behaves like a Faraday cage owing to the screening effect of the metallic wire.
- The method according to the invention makes it also possible to employ as metallic wire 12 a copper wire with a coating of gold and/or silver.
- When the
composite yarn 11 according to the invention has been knitted or woven, it may happen that the textile part of the fabric undergoes a required controlled shrinkage so that small segments of themetallic wire 12 may come to the surface; the shrinkage of the textile part may occur by washing the fabric for instance. - The metallic wire, emerging in segments from the
composite yarn 11 forming the fabric, comes into contact with the wearer's skin. This contact is sought for and desired since it enables thecomposite yarn 11 to act not only as a Faraday cage but also as a conductor, thus making uniform the electrical charges in the body of the person wearing the garment made with thecomposite yarn 11 according to the invention. - In fact, it has been found that in this way the
composite yarn 11 according to the invention makes possible the attenuation of the differences of electrical potential created within the body and deemed to be the cause of pains associated with the breaking of bones.
